【摘要】：目前我國已經(jīng)成為水產(chǎn)養(yǎng)殖大國,養(yǎng)殖產(chǎn)量和規(guī)模都位居世界前列,但隨著養(yǎng)殖種類的增多,傳統(tǒng)粗放式養(yǎng)殖易造成水體污染,給水產(chǎn)養(yǎng)殖行業(yè)帶來巨大的經(jīng)濟(jì)損失。因此,利用新興技術(shù)及時準(zhǔn)確的獲取養(yǎng)殖環(huán)境數(shù)據(jù),合理增氧、科學(xué)投飼成為一種發(fā)展趨勢。在這種背景下引入物聯(lián)網(wǎng)技術(shù)可以使養(yǎng)殖生物生長在最適宜的環(huán)境里,對提高養(yǎng)殖產(chǎn)量,達(dá)到高產(chǎn)高效的目的,具有重要的意義和應(yīng)用前景。本文根據(jù)物聯(lián)網(wǎng)的三層架構(gòu),設(shè)計了基于物聯(lián)網(wǎng)的水產(chǎn)養(yǎng)殖測控系統(tǒng),本文主要完成的工作如下:(1)針對養(yǎng)殖水域空曠無遮擋的特點,構(gòu)建了由太陽能供電的水質(zhì)監(jiān)測節(jié)點,以減少線路腐蝕帶來的維護(hù)成本。該節(jié)點對水質(zhì)中的水溫、溶氧和pH進(jìn)行監(jiān)測,采用標(biāo)準(zhǔn)的MODBUS-RTU協(xié)議進(jìn)行水質(zhì)參數(shù)傳輸。(2)構(gòu)建了由光耦繼電器和交流接觸器組成的設(shè)備控制節(jié)點。其中,光耦繼電器接收到指令后,繼電器控制交流接觸器吸合或斷開,從而控制連接在交流接觸器上的設(shè)備開啟或關(guān)閉;光耦繼電器利用光耦信號獲取設(shè)備運行狀態(tài)。(3)根據(jù)需求構(gòu)建了嵌入式網(wǎng)關(guān)的硬件部分。該部分主要包括SIM900A GPRS模塊、STM32單片機(jī)、RS485通信接口、時鐘模塊、存儲模塊以及電源模塊。(4)構(gòu)建了水產(chǎn)養(yǎng)殖現(xiàn)場的ZigBee無線傳感網(wǎng)絡(luò)以減少布線。水質(zhì)監(jiān)測節(jié)點通過ZigBee網(wǎng)絡(luò)將采集的水質(zhì)參數(shù)發(fā)送到嵌入式網(wǎng)關(guān)。同樣,嵌入式網(wǎng)關(guān)接收到指令后,通過ZigBee網(wǎng)絡(luò)將指令發(fā)送到設(shè)備控制節(jié)點,設(shè)備控制節(jié)點反饋執(zhí)行狀態(tài)。(5)設(shè)計并實現(xiàn)了由嵌入式網(wǎng)關(guān)、服務(wù)器和Android客戶端組成的軟件部分。嵌入式網(wǎng)關(guān)實現(xiàn)了養(yǎng)殖環(huán)境數(shù)據(jù)上傳、監(jiān)聽服務(wù)器的指令并進(jìn)行實時數(shù)據(jù)獲取、增氧機(jī)和投飼機(jī)的遠(yuǎn)程、定時以及自動控制;服務(wù)器實現(xiàn)了嵌入式網(wǎng)關(guān)與Android客戶端之間的通信、養(yǎng)殖數(shù)據(jù)存儲以及Android客戶端數(shù)據(jù)查詢接口;Android客戶端設(shè)計了人機(jī)交互界面,并實現(xiàn)了實時養(yǎng)殖數(shù)據(jù)展示、三種模式的設(shè)備控制、歷史數(shù)據(jù)查詢等功能。
[Abstract]:At present, China has become a large country of aquaculture, and the production and scale of aquaculture are among the top in the world. However, with the increase of species of aquaculture, the traditional extensive culture can easily cause water pollution and bring huge economic losses to the aquaculture industry. Therefore, it is a development trend to obtain the data of breeding environment timely and accurately, to increase oxygen reasonably and to feed scientifically. In this context, the introduction of the Internet of things technology can make aquaculture organisms grow in the most suitable environment, which has important significance and application prospect to increase the yield of aquaculture and achieve the purpose of high yield and high efficiency. According to the three-layer architecture of the Internet of things, this paper designs a measurement and control system for aquaculture based on the Internet of things. The main work of this paper is as follows: (1) aiming at the characteristics of open and unobstructed aquaculture waters, a solar powered water quality monitoring node is constructed. To reduce the maintenance costs associated with line corrosion. The node monitors the water temperature, dissolved oxygen and pH in water quality, and transmits the water quality parameters by the standard MODBUS-RTU protocol. (2) an equipment control node composed of optical coupling relay and AC contactor is constructed. After receiving the instruction, the optical coupling relay controls the AC contactor to be sucked or disconnected, thereby controlling the device connected to the AC contactor to open or close. The optical coupling relay uses the optical coupling signal to obtain the running state of the device. (3) the hardware part of the embedded gateway is constructed according to the requirement. This part mainly includes SIM900A GPRS module STM32 single chip microcomputer RS485 communication interface clock module storage module and power supply module. (4) ZigBee wireless sensor network in aquaculture field is constructed to reduce wiring. The water quality monitoring node sends the collected water quality parameters to the embedded gateway via ZigBee network. Similarly, after receiving the instruction, the embedded gateway sends the instruction to the device control node through ZigBee network, and the device control node feedback execution state. (5) the software part composed of embedded gateway, server and Android client is designed and implemented. The embedded gateway realizes the data uploading of the culture environment, monitoring the instructions of the server and real-time data acquisition, remote, timing and automatic control of the oxygenator and the feeder, and the communication between the embedded gateway and the Android client, the server realizes the communication between the embedded gateway and the Android client. The man-machine interactive interface is designed for the storage of aquaculture data and the Android client data query interface. The functions of real-time breeding data display, equipment control of three modes and historical data query are realized.
